Case report: Ensitrelvir for treatment of persistent COVID-19 in lymphoma patients: a report of two cases.

Persistent COVID-19 is a well recognized issue of concern in patients with hematological malignancies. Such patients are not only at risk of mortality due to the infection itself, but are also at risk of suboptimal malignancy-related outcomes because of delays and terminations of chemotherapy. We report two lymphoma patients with heavily pretreated persistent COVID-19 in which ensitrelvir brought about radical changes in the clinical course leading to rapid remissions.

Polatuzumab vedotin pharmacokinetics in a hemodialysis patient with diffuse large B-cell lymphoma.

Purpose: Chemotherapy for the hemodialysis (HD) patient is a challenging situation because it requires special considerations including dose modifications and timing of drug administration in relation with HD sessions. Polaltuzumab vedotin (PV), an antibody-drug conjugate in which monomethyl auristatin E (MMAE) is linked to an anti-CD79b monoclonal antibody, is an extremely promising therapeutic for treating diffuse large B cell lymphoma (DLBCL), but the pharmacokinetics are unknown in HD patients.

Methods: We carried out pharmacokinetic studies of PV when administered at 1.

Induction of Oxidative Stress and Cell Death in Neural Cells by Silica Nanoparticles.

Silica nanoparticles (SiNPs) are produced on an industrial scale and used in various fields including health care, because silica is stable, inexpensive, and easy to handle. Despite these benefits, there is concern that exposure to SiNPs may lead to adverse effects in certain types of cells or tissues, such as hemolysis, immune responses, and developmental abnormalities in the brain and developing embryos. Although investigations on the toxicity of SiNPs against neurons are essential for medicinal use, only a few studies have assessed the direct effects of SiNPs on cells derived from the central nervous system.
